the and sign: '&' is not different color nor is the [ and the ] a diff color it is all white.

colorization is a powerful tool to make programming and oversight easier IMHO.

Or is this issue of wxpython library?

Thanks,Vincent

p.s. keep up doing the good work

No it is possible to have operator characters colored differently I just have them using the default style in the default style sheets.

To set a custom color for them open the style editor (Tools=>Style Editor), then select the 'operator_style' tag from the list box and set the foreground/background color you wish for it to be in the right side of the dialog. Once all is how you want it just click on export and give the sheet a name you like. It will automatically be set as your preferred style and will update all open buffers to use it.
